The Climate and Aerosol group at UC Irvine (www.ess.uci.edu/~zender) seeks full time graduate student researchers with enthusiasm for modeling problems in atmospheric and terrestrial physics, climate, and chemistry. We use sophisticated numerical models of the Earth system to improve understanding of aerosols, trace gases, and clouds in the climate-chemistry system. Topics which we are interested in pursuing as student projects include: Processes and mechanisms responsible for observed changes in mineral dust aerosol at interglacial/glacial transitions Bioclimatic controls (vegetation, precipitation) on dust emissions Non-linear effects in aerosol absorption, scattering, and extinction Role of precipitation scavenging and cloud geometry in trace species budgets Role of boundary layer instability in dust emissions Partitioning natural from anthropogenic dust emissions Mesoscale processes and mechanisms of dust entrainment and deposition Integrating wind and riverine erosion into a single model Simulating the effects of absorbing aerosol on snow and ice albedo Indirect effects of dust and sea salt on precipitation Biogeographical distribution of vulnerability increased erosion under climate change
